Thanks,
I was folowing this exact tutorial https://www.espruino.com/USB
but I was not getting any result. I changed the code a bit to see if it was actualy doing something.
The final code is the one on the image I sent above.
The leds were turning on but no text was sent to the computer.
First some background:
I am using a Sony vayo with AMD processor.
The First time I tried to use the pico on it the correct driver was not installed.
In the link https://www.espruino.com/Quick+Start+USB
I saw the message Non-Windows XP users download version 1.4.0 drivers. ... dpinst_amd64.exe for 64 bit systems.
As my computer was an AMD I tried this driver an it solved the problem. The pico was recognized and I could use the IDE.
Now
I tried to use the code of the Example "USB and USB HID Keyboard" without success.
I searched the web and I finaly came to this coments in the forum where Gordon said that the code was working on his windows 10 but user user79809 said that it was not working on his.
So I decided to try the pico on another windows 10 computer this time an Intel one.
And voila... it works as a charm.
So I have a pico with the keyboard "hello world" code that works on the windows 10 intel but does not on the AMD.
I believe it must be a Driver issue. (dpinst_amd64.)
PS. In the AMd the leds work but no keyboard character is sent to the computer.
